The last time someone tried this, it was the last reel of the movie version of the game: "Doom". That didn't work out very well. This one isn't just one reel, but the entire movie.... Still, I'm sure the novelty effect alone will get a good audience for the opening weekend. Does anybody wanna take bets though, on how many viewers leave the theatre dizzy, heaving and puking?

I'd be interested in the BTS making-of for this project, more than actually going to see the movie.

This movie is pitched to the first-person-shooter "gamer"community. But the thing I wonder about is, gamers like the POV because they're controlling it themselves. In the movie, it's a passive ride. Though there is a LARGE segment of game play videos and an audience for those recordings of actual FPS game play, they tend to be short, not movie-length.

Me, I like to watch the cinematic "cut scenes" from these games, but I find the actual game play uninteresting by comparison.
One exception might be a movie based on the game: "Mirror's Edge". That one is so stylistically unique, it might hold a general audience's attention where something like GTA, COD or Battlefield wouldn't.
